Extends the capability model to the nine WP-0003 engines (~23 systems total). Per-shard spectra 13 -> 14 (adds provenance granularity); refines merge-model (+fork/journal-replay, +coexist-with-rank), attachment-mode (+git-IS-store, +container, +direct-DB, +REST/file-store-hybrid, +external-API payload-format facet), native-query (+SPARQL/RDF far-end), history (+DB-rows, +partial), structure (+typed-graph, +inline-embedded objects), content-opacity (+lossy-exportable), write-granularity (+story-item, +section-anchor). Headline: new federation-model taxonomy (S2.5) -- federation is plural (fork+journal / VCS-replication+ping / query-time graph join / feed aggregation / activity streams / engine-mirror), a selectable/composable coordination-layer axis feeding SHARD-WP-0002 T1-T6. Folds UC-68-82 into the workplan; no new UCs, no INTENT boundary change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Exploration results for the problem and solution space.
Each exploration uses a yymmdd- prefix on the markdown file or subdirectory
when multiple files or sources are involved. Findings here inform spec/ and
SCOPE.md; they do not directly authorize implementation until promoted.
